Features and benefits
Typical applications
RN chokes are attenuating common-mode or
High saturation resistance and excellent
Phase-angle control circuits in combination with
being connected in series with the phase and
Through hole pin connections.
EMI input filters
asymmetric (P/N –> E) interference signals, by
neutral lines of an AC powerline input.
Symmetrical components of the noise are also
attenuated by the leakage inductance of the
windings. These chokes are typically used in
conjunction with suppression capacitors.
thermal behavior.
Dual-choke configuration.
Small compact design.
Multiple housing options.
Custom-specific versions are available on
request.
